Should brand-name drug makers be held liable if consumers are harmed by a medicine made by a generic rival?

The Alabama Supreme Court believes the answer is yes. And the court has upheld its own controversial ruling that Pfizer PFE -0.31% can be sued by an Alabama man who claimed he was injured by a generic version of its Reglan heartburn medicine. Why? The brand-name drug maker purportedly failed to warn his physician about the risks.
